Info for care page: Stainless steel is dishwasher safe & easy to maintain. Caring for your stainless-steel flatware properly can help preserve its luster & longevity for many years to come. It is important to always follow the below suggestions for use and maintenance. It is also important to know stainless steel is stain resistant but not stain proof, and if subjected to unfavorable conditions can corrode and stain. Follow these tips below in caring for your flatware. 

  • Wash thoroughly before first use. 
  • Do not allow food remnants to sit on your flatware for a prolonged period. Remove all food soil from your flatware immediately after use. Some foods are very harsh to the stainless steel and can cause pitting, corrosion, discoloration, and etching. These foods include but are not limited to: Vinegar, Salt, Mustard & Mayonnaise. 
  • Avoid soaking your flatware before washing. Soaking flatware is not recommended. However, if stubborn food is difficult to remove, let set in warm water with a mild detergent for no more than 10 minutes. Do not soak for extended periods of time or overnight, as minerals & salts commonly found in tap water can lead to corrosion, unwanted staining, or film buildup. Avoid soaking in or with aluminum or copper materials. Use a chloride & chlorine-free solution for all steps of cleaning. 

Washing your flatware 

If using a dishwasher, load forks and spoons handle down and avoid “nesting.” Place knives in a separate section of the basket with the blade down to prevent scratching and contact with other metals. This is especially important if the flatware is plated or contains a coating. We recommend using a flatware basket that separates each piece. This is important for dishwashing your plated, chromium, or titanium coated products.  

It also is important that you follow your dishwasher manufacturer's instructions regarding the amount of detergent to be used. Cambridge recommends Cascade Complete Gel Packs (with Dawn grease fighting power) for dishwashing. Hard or Soft Water? If you use too little detergent in hard water, flatware will not clean as well. If you use too much in soft water, flatware can etch or even rust, which is why we recommend Cascade Complete Gel Packs; they have additives included in the detergent to help control the PH level of the water.  

When hand washing, use hot water and mild detergent. Dawn is ideal for hand washing. Do not use metal scrub brushes, scrapers, or steel wool. Do not use the scouring/abrasive side of your sponge when hand washing. This can lead to scratching and can increase the risk of corrosion. Rinse thoroughly, dry with a soft towel and store. Air drying is not recommended.  

Whether washing by hand or with a dishwasher always avoid washing with or in aluminum or copper kitchen items. Never use dishwashing liquid that contains harsh chemicals, lemon scent, bleach, or chlorides. 

Drying & storing your flatware 

In a dishwasher it is best to use a rinse aid. Rinse aids help remove water from flatware & can reduce drying time. Rinse aids keep water from forming droplets that can dry as spots or streaks. If hand washing, avoid air drying, use soft cloth to dry and store in a dry place until further use.  

When cared for properly, Cambridge flatware should never need polishing, however if hard water stains, mineral build up, water spots, or detergent stains appear on your flatware you can use the following guidelines. Wipe down with a cloth dipped in vinegar until stains disappear. Once stains are removed, clean the items to assure the vinegar is removed. This will also add brightness to the flatware and bring its luster back. Periodically, you may choose to use a polish to remove any film buildup or staining from your stainless flatware. Be sure to use a polish specifically made for stainless steel. Once polished, it is always important to rinse thoroughly. Stainless steel polish is made to be used on stainless steel; It is not designed for use on flatware that is plated or coated. 

Has a brushed or satin finished item become dull? Grocery store purchased Scotch-Brite pads can be used to correct the finish. Simply place the item between a folded pad and gently move the item up and down, parallel with the length of the item. 

Knife blades are particularly sensitive to acidic foods, being soaked in water and air-drying. Therefore, it is particularly important that you wash your knives promptly after each use, and dry immediately. Do not store in plastic or other wrappings that may trap moisture. Keep knives and other hollow handle flatware away from any open flames or other sources of extreme heat. 
You should not try to sharpen knives that have serrated edges which could result in damage to the blade.
